CrabClaw

The CrabClaw uses an opening jaw design to simplify
arthroscopic knot tying and suture management. The jaw can be opened to grasp
the suture strand anywhere along its length, avoiding the time consuming task
and “fiddle factor” associated with threading suture onto conventional knot
pushers. The opening jaw is particularly useful when checking suture strands
for tangles and for quickly changing the suture posts when tying arthroscopic
knots. It is also possible to pre-tie multiple half-hitch knots and advance
each one down the cannula quickly and efficiently, securing an arthroscopic
knot.
